Balsamiq Wireframes (balsamiq.com/wireframes) is the industry-standard for rapid low-fidelity wireframing. It combines the comfort and simplicity of paper sketching with the power of a digital tool, so your work is easier to share, modify, and get honest feedback on.
Wireframes look like sketches, so stakeholders don't get distracted by little details, and can focus on what's important instead.
Balsamiq is a small and personable company that competes on usability and customer service. Balsamiq believes work should be fun, and that life is too short for bad software.
Balsamiq Wireframes is available on the Web, on Desktop, and integrated with Google Drive, Confluence, and Jira.
